Plastic: Reduce the use!

ערימת פסולת פלסטיקAbstract: This module is designed in purpose to expose the students to the convenient use of plastic products on the one hand, and to the environmental impact caused by over-using those products on the other one. We, the developers of this module, wish that this module will develop the sense of responsibility of chemistry students to the environment, by increasing their awareness to the environmental impact of imperishable polymers and by exposing them to other possibilities such as recycling and alternative exhaustible materials. They might be our ambassadors in their houses.

Developed by: Sandra Azuelos-Kats, Afrah Assi, Pavel Kuzmin

Can used oil be the next generation fuel?

מכונת דלק בשדה חמניותAbstract: Energy crisis is here. With the increase in world population the demand for fuel and energy sources is increasing too. Most of the energy sources are derived from petroleum. These sources pollute the environment. One of the alternative energy sources is biodiesel, and it derives from plants or from used oil plants. Through the module we can expose the students to existing energy sources and the alternative biodiesel.
